RS-4600

RIGID MICROWAVE ABSORBING MATERIAL – RS-4600

RS-4600 is a rigid epoxy based magnetic castable microwave absorbing material capable of continuous operation up to 350of. This material is ideal for fabrication of low power loads, attenuators, ring chokes and other RF absorbing elements at microwave frequencies. RS-4600 can be supplied in custom cast configurations, standard stock shapes of plates, rods and bars, or in pourable kits.
